best wire for SUT trannies?

[rockdoc]

I'm about to wire up my box with 2 Partridge 977 trannies I just put together. Wondering about wire recommendations....

I've been liking ~22 AWG solid core copper in clear teflon sleeve. Very flexible, easy to route.

Best wire for a step-up transformer? Um... Conductive wire... 😉 If the transformer is used at line level I'd use some good microphone cable such as the Canary Star Quad cable.

Tinned copper wire with insulation? Erm, I don't get what the issue is... Certainly use twisted pair, that's pretty much a given for any signal wiring.

 

[rockdoc]

no real issue, just wondering what others have done. I have never seen twisted pair wiring in any SUT though..... Steve T

A quick google for Partridge 977 brings up this example where someone used lamp cord: https://www.hifido.co.jp/sold/18-18403-42679-00.html?LNG=E

Twisted pair would be a good option if you don't want to use shielded cable.

Reading the thread title i assumed someone here has finally figured step up trannys need better wire. C'mon, even midfy Per is offering Cardas... But no, it's just another pointless lamp cord/wire hanger thread.

Is the wire for the trannies to hold their dresses up?

The transformers should be mechanically well fixed. The input and output (RCA) connectors should be mounted close to the transformers' terminals. I prefer very thin bare solid silver wire between them. A very thin uninsulated copper wire would also do. Ideally the wire length can be below a couple of cm (2" or so). There is no point using shielded cable.

No silly, it’s to restrain them!

Oh, you pervert!!!

thanks for your reply Icsasar. What's the advantage of uninsulated wire?

I use 19AWG kimber teflon insulated wire in mine as well as tinned copper wire for jumpers. Solid silver jewelers wire is another good option. (Slip it into teflon tubing for insulation where required.)

If you are using an MC with particularly low source impedance into a transformer with a low primary DCR and relatively low inductance the quality (read as wire DCR and contact resiistance) of arm wiring and the arm cable may also be important.

You don't have to worry about the adverse effect of wire insulation.

Thanks Kevin! Good to know. (by the way, I'm Steve T who came up and bought a pair of your MkIII dynacos years ago. Great amps but long gone. Hope you're well!)

Nice to hear from you, that must have been well over two decades ago.. LOL Closed up shop and moved on to steadier employment. (Or so I thought in 2000.. 😀 )
